Product Description
APV400 Intelligent Valve Positioner operates on the principle of piezoelectric valves and is equipped with HART communication protocol. It effectively converts a 2-wire 4 to 20 mA control signal into pneumatic output for the actuator, making it suitable for both pneumatic linear actuators and rotary actuators. This functionality enables precise positioning of the valve according to predetermined settings. The positioner features a compact and modular design that offers high cost-effectiveness. Its self-tuning capability for control parameters, combined with excellent adaptability, significantly reduces setup time while ensur ing optimal control performance.
Features
· Adaptive predictive control algorithm for faster response and more precise control.
· Automatic detection of valve lower and upper limits, opti mizing valve control parameters to enhance accuracy.
· Dot matrix LCD display with multi-language support, ro tatable by 180° for easy observation. Equipped with four configuration buttons for local valve control and settings adjustments.
· Supporting parameter configuration for split range, characteristic curves, stroke range and direction, tight closure, dead zone, control parameters, digital input, alarm and fault outputs, and more.
· Diagnostic capabilities include leakage detection, partial stroke testing, upper and lower limit monitoring, pressure and temperature diagnostics, stroke accumulation, directional change counts, and piezoelectric operation monitoring.
· IDM software allows setup and calibration of valve accessories, with status monitoring and alarm tracking.
· Compatible with HART 5 and HART 7 communica tion protocols.
· Including one isolated digital input and two dry con tact inputs.
· Digital output with electric isolation provides alarm or fault notifications.
· Electrically isolated position feedback block outputs 4 to 20mA position feedback.
· Optional "faillast" function ensures operational stability during power, gas, or signal failure.
· Equipped with surge protection for enhanced reliability.
